clean up after yourself - this means bus your dishes and glassware. make your bed, keep the area you are sleeping in tidy, keep your bathroom space clean. put the toilet seat back down, especially if there are women in the household.

when in rome - follow their schedule as much as you can, this means, don't keep them up until 4am when it's a work night. you are on holiday, they are not.

send a thank you card, or phone call after you've left.

I try to leave a small gift, since staying with someone obviously saved me a lot of money, I try to spend some of it to beautify their home with something personal but matching. You can also just bring flowers when you leave.
